If a girl has custody of a kid with the dad getting her every other weekend what would happen if she

wanted to move a few states away?

you have to get permission from the father and the courts. If you leave the state without letting the father know it would be considered kidnapping. And you need it in writing.

Agree with niteowl on that! You have to also look at it like this if the shoes were on his feet would you like that to happen to you
